Ion Exchange

Chemical processing requires advanced and precise operating techniques and procedures. DuPont Water Solutions products address a wide range of separations, catalysis and purification needs across the entire operations workflow. For decades, we have been the premier supplier of polymeric ion exchange (IX) resins that are used to produce, purify, and recover some of the most commercially important elements in the world. We specialize in catalysis and separation technologies, as well as industrial water treatment, and feature some of the most recognized brand names in the industry.

Reverse Osmosis

Filmtec RO technology provides an industry-leading, high performance, reliable, and cost-effective solution for chemical & petrochemical applications.


DuPont's IntegraPac UF membranes provide the right solution in the chemical & petrochemical industry for containerized systems, groundwater, industrial water pretreatment, surface water, or water reuse. Also common for protecting downstream RO elements.


EDI technology is a smart alternative to, and effective replacement of, conventional mixed bed ion exchange. And since electricity is EDI’s only consumable, this method of permeate polishing does not produce a hazardous waste stream, allowing power plants to produce continous high purity water while saving time, money, and space. DuPont EDI-210 and EDI-310 ion exchange modules contain a gaussian, gel, strong base anion exchange resin for industrial demineralization.

Case Study

Nanofiltration Produces Sparkling Clean Water for Swedish Resort Community
Lofsdalen, Sweden, had an outdated water treatment process complicated by variable water quality from an unreliable source. Using FilmTec™ NF255-400 membranes, the town could pull water from Lake Lofssjön, remove the contaminants, and provide sparking clean drinking water to the town residents and tourists.
FilmTec™ NF270-400 Element Helps National Park Service Improve Water Quality
The Denver Service Center of the U.S. National Parks struggled to treat tricky water that needed to meet EPA secondary Standards. Check out the full article to see the raw water constitutes, met requirements, and reduced operational cost.
